I wouldn't use Con basically for all the reasons mentioned, plus:
It is independent on how many surges you had originally, and this is also greatly affected by your role. In the end, Defenders will lose their (necessary) healing surge advantage.
It would be better to base it on the actual number of surges they have. Maybe 1/2, 1/3 or 1/4 (rounding as you prefer, mimimum 1 surge).
One idea I had at the start of 4E was to have something like a "Recharge" roll - roll 1d6 for every surge you normally have after an extended rest.
Reaching or exceeding an arbitrary number as dependent on your "grittiness" level (e.g. on a 2-6, or 5-6, or 6 only), you recharge one surge. A drawback is the amount of rolling required, but then, it is still a simple process. You could even add a degrading aspect to it - you only get recharge rolls for surges you had since your last extended rest, so it is bound to get worse each day. (In that case, a low Recharge number seems most appropriate.)
I would probably suggest something like Recharge 5-6 if you roll for all surges and 3-6 if you roll for surges you have recharged since you're last extended rest. 5-6 means on average you recover 1/3 of your surges, 4-6 you recover about 1/2, meaning 1/4 ofter 2 rests, and 1/8th after 3 rests.
Or you could just use a fixed number based on role itself.
Controller get 2 surges back, Leaders and Strikers 3, Defenders 4. Doesn't account for the differences in healing surge numbers between classes of the same role that we see in practice, though, but it gets closer than using Con. If you still want Con to figure it, you could add a Constitution or Endurance Check to recover 1-3 additional surges. (maybe based on class role).
