Played it a little on dev, its a complete nerf to anyone unfortunate enough to have rolled AR/Dev, there is zero benefit in this change significant detriments to it and the bonus range to psi is just galling.
Its cool that you are trying stuff, kudos, and I can see this having some benefits in the "vanilla" formula blaster sets but given that all things are not equal a sweeping change across the board is a terrible way to do things.
If you do go ahead with things in this vein, and I personally thing you should try things with a wider audience to see what happens, I have faith that should it be a negative change it wont go ahead or will be changed, but then I still think things can slip through the cracks which are unintended, I know this from my own experience in this field.
I would strongly suggest a AR sniper rifle and targeting drone synergy giving AR sniper rifle back the range its used to, tying them together (like the weird little bonus damage they gave sniper rifle + targeting drone) would prevent better synergies from becoming unbalanced.
Just my 2 cents from having rolled a AR/Dev to gauge the benefits of perma "fast snipe", with proposed changes I would can it, strip the enhancements and play a different blaster of which theres lots of choice, I wont be hurting for something to do.
