Would I?
Yes
But you have to decide if you can live without the EFOV of 320mm
Agree. but I personally would miss the 320mm equivalent. Additionally, the 105 on a FF is in fact 105mm. Not that much of a reach. His current EF=S 15-85mm is just as wide and has a longer reach with its FF equivalent of 24-136. While the 24-105 is a constant F4, compared to the 15-85 its only a 1/3 pf a step faster up to 35mm (56mm FF equivalent). If the 24-105 was f2.8 then maybe it would be a no brainer. While the IQ of the 24-105 may be a bit better, the 15-85 is no slouch. Considering the OP is only using his gear for family snaps and vacation photos, you have to wonder how much of this is just his desire to get a new toy with an L lens.
I can understand the limitations of his current body, both in features and ergonomics. I personally find the Rebels uncomfortably small, and my hands are not very large. Unless he has a compelling reason to go FF I would keep the lenses and upgrade the body to a 7D.
