Don't do this.
I get you want to restructure classes, maybe to give them more identity and customization through choices - but this is not the way.
I have played WoW for 15 years. I have played SWG pre NGE. I have played a bunch of MMOs over the years. And if I can tell you one thing - senselessly pruning classes, condensing them down so even a 6 year old can play the game - and then feed your players the pruned abilities back as "choices" in a skill tree is bad. If you really want SWTOR to burn to the ground, be my guest and implement this. But your players will not like it.
If you really want to shake things up then take this back to the drawing board. Have it delayed to the next expansion (8.0). Give it YEARS of PTS so your players will be happy in the end. THAT is how you rework your classes, not internally with less then 5 months going until release.
In the meantime just implement it so force users can choose whatever force tree is currently in the game (with dark side/light side restrictions) and tech users can use whatever tech tree is currently in the game. That alone is perfectly fine and will make your players happy as they just can be.
No one asked you to completely rework and prune classes. So, either don't do it at all or if you really want to give it more time. But not this <5 months until the xpac.
