It wouldn't be crazy to try that.
That's what we usually do BUT, we typically use the single rider line at TT, so our wait there is not that long.
We have often been in the first wave at Soarin, then gone from there to TT and from there to MS and been through with all 3 of them by a little after 10. Going standby at TT would obviously slow that down.
If you went to TT first and then to Soarin, but decided that the line there was too long, at least you'd get to do each of them once.
