First, as an aside, agreed with Elektra, though I'd think even more coverage. YMMV.
I have a vague recollection of a female ninja, also in Clix, but no further help. Sorry.
However, proving I CAN be on topic:
If one is thinking of proxying Irregulars into ST-for-FT, one could do far worse, and little better, than seek TMP posts, and the blog of, Colgar6. Hugh has done a lot of effort in that direction, and better to improve on, rather than reinvent, the wheel.
There have been button-Enterprises before, but that's a much harder search. Suffice, you are doing fine effort in a path already trodden.
I'm also a fan of GW-guns-to-spaceship conversions, though I think I'd lose that wire stock. Usually, I envision Tau guns as 'bricks' and other items as in wholly their own fluff, but can't quibble with your choices.
When BFG was young, GW even encouraged folk to make their own bioships from 'nid parts, though they assumed you'd buy whole kits rather than bummng spare parts off of friends, as I used to. ;->=
