This is going to be a long one cause I will break it down point by point as to why we will never see an improved V1, or a 2 in 1, or a stripped down Joker.
Main reason being HT will be reissuing a third run of V1 Joker this March. Will not make sense for them to release an improved V1 Joker a few months down the line. It will be stupid business decision cause this will alienate a lot of collectors and the 12 inch business relies on regulars. This is the type of hobby that only a few can afford and you will want to keep whatever customers you have happy.
The HT suit is as good as it gets for a mass produced figure. Those minor changes wished here (slight colour change, minor tailoring and pattern change) are not a strong enough incentive for HT to risked releasing a figure that will definitely sell way less. It will be lucky if it sells even half the amount of V1 Joker.
Also, HT has never actually released an 'improved' figure per say for the same line. Predators got more accessories and battle damaged but it is still essentially the same sculpt and as evident from the Predator threads here, still full of inaccuracies.
I also do not forsee a 2 in 1. The only 2 in 1 ever done was Superman and that was a few years ago. It was a time where HT was still experimenting with the market, testing the waters. With the rapidly rising costs of figures no one will pay for a 2 in 1 these days. I think 2 in 1 supes back then costs only slightly more than a standard HT figure and that was a few years ago. Today, it will probably be about the price of a Batpod.
HT knows that customers are tightening their belts and are getting choosy about what they spend on. It's evident with TF. HT could have easily included a burnt white shirt along with the figure since they included another jacket but they didn't to lower the cost. This was actually the reason giving by HT as to why they didn't include the burned white shirt also.
Enterbay FOF Bruce Lee was a two in one. One body, two headsculpt, two set of clothes and despite an edition size of 5000 it ain't exactly flying of the shelves. You can still order one direct from Enterbay. I can still walk into a store and buy one any day.
Many collectors I spoke with would have gladly pay for a cheaper BL with only one headsculpt and one set of costume. But being forced to buy a 2 in 1 set, many felt that it wasn't worth it (me included and I am a BL fanatic).
The stripped down joker wouldn't work either. The Cannibal Jack Sparrow was a poor example because he was release without a coat and hat because Cannibal Jack didn't have the coat and hat with him in that scene. Hence he didn't come with one.
Cannibal Jack was never about selling a simplified Jack Sparrow. He could have been wearing a totally different costume for that scene and HT would have then released him with a totally different costume.
The main selling point is really the whole cannibal Jack look and it was a really funny and memorable scene. The extra smiling face is really HT way of giving a better headsculpt for those who bought the AWE Jack. If you don't have an AWE Jack, well, you have a bonus headsculpt to play with. They did the same thing with BR Joker. If you have a V1 Joker, great, now you have the ULTIMATE Joker. If you don't you still have a great figure with an extra head to play with.
All signs actually point to nurse Joker. It was a memorable scene with a really interesting look (wig) and accessories (the board, detonator, "I believe in HD Sticker"), and costume (nurse, sneakers). The situation is very similar to the Cannibal Jack Sparrow in fact.
A really unique look from a very memorable scene. This one has a higher chance of selling more than a slightly improved V1 Joker.
