How hard would it be to make my own color test jig?

[Electronic M]

I have worked on a few tube and hybrid, round and rectangular screen color TVs, and whenever I do I start to hate pulling and reinstalling the chassis repeatedly. I was thinking that it would be better to use a small inline tube to eliminate having to deal with dynamic convergence, and because inline tubes are cheap and plentiful. Is this a good idea? And would it matter much which CRT I use? I was thinking of using this working Trinitron SD-59 I've had sitting around for a long time would this be a good choice?
