Tapping into HVAC?

Pretty sure I've seen it discussed on here before, but I'll explain my whole situation..

Contemplating an attic room, I noticed the best potential space had a flaw, which may be a blessing..
In the middle of the future floor is the air return in the ceiling of my bedroom.

Would I have any issues if I removed the return line and use the vent to for air intake to the grow space, and install the return to my filtered exhaust dumping it right back to the air return junction?

Or would that make the thermostat read warm, therefore not letting the heat turn on? Or would that even matter while constantly dumping 80° air in the house?

Other potential issues?

Thanks in advance!
