Another great idea from Julia!
The version below uses two Locusts to reduce pieces from [4+8] to [5+4]
The eight squares adjacent to the bK are vacant.

Very nice idea indeed from Julia showing the black queens interchanging roles to form batteries. Chameleon echo mates and the different moves of black pawn f7 add to the variety, The different check to the black king is good too.

But I feel that the play is mostly around the white king, while the black king is tied up and ready to be checked. Perhaps the idea (except the part of white checking black) is better shown as a Helpmate I think.

You are right. As a helpmate the white queen transformations would be lost. While a mobile black king will be welcome, what I meant was that none of the black moves set up the black king.

Dear Julia,
I suppose it was the sight of the stationary mass of four bPs and two wSs surrounding the bK which upset my aesthetic sense. However if you do not mind such an idea then perhaps you would like the following version. It has the merit that the units surrounding the bK are all Ps, there are no wSs and the only pieces are the three thematic. There are now two solutions and the condition ChameleonChess applies.
[Our opinions differ regarding the use of Locusts in my previous version].

I forgot to mention the possibility of replacing the bPf7 with bSa7b7. The solutions being:
1.Qg4-e6=S Qh7*h3=S + 2.Kg5-h4 Sa7-c8=B 3.Se6-f4=B + Sh3*f4=B #
1.h3-h4 Qh7*h4=S 2.Kg5-h5 Sb7-d8=B 3.Qg4-f5=S + Sh4*f5=B #
The bSs reinforce the chameleon theme very nicely.
I know that having two knights for one pawn will cause panic in some circles – but that is what I would choose!

Dear Julia, I saw your problem n.100 just now. I like it! The change of functions between black cQs and the set form of problem is really nice!
About another versions:
-I agree with you that using of technical fairy pieces (as in the version with Locust) is not acceptable;
-The another version by Peter Harris is also not an improvement because there is lost the nice change of functions by the black cQs.
About the replacement of bPf7 with two cSs – this is not good in my opinion because in both solutions one of this Knights is idle. This is not an good option…
So in conclusion – I think that the original published problem is the best choice.
By the way – Seetharaman Kalyan really use this mechanism for H# problem as he noted above and dedicated it to you. Here is the link: http://kobulchess.com/en/problems/chameleon-50-jt-2012-originals/144-chameleon-jt.html
