Nah, not really. It wouldn't be any more difficult to bring down the town, per say. Two flight of bombers carpet bombing as they did in WWII would still bring it down in 1 pass. The Hordes do one thing over a unit more inclined to use "tactics": they level the base and prohibit any form of defense from forming. Having the hangers leveled is what hordes do, the town wouldnt need any more work than it currently does, really. Two more 1000 bombs, and an extra strafe run by a Mossi or Bf110 on strategic points near the edge of town and BAM there ups the ominous and easy-mode white flag.
All good in theory, but practice never works out quite like we expect. Especially since the area our bombers clear is relativly narrow. If we had the ability to adjust the width of our bomber formations, yeah, it wouldn't be as hard. But "wouldn't be as hard" and "is relativly easy" aren't the same thing.
Bombers are pretty slow and you can see them coming for quite a ways. That means uppers. Uppers means your goon or M3 dies. Troops dead means no capture.
While its pretty straitforward, the issue is that it relys on several assumptions that rarely work out to be true:
1) nobody ups to kill the bombers
2) bombers and whatever ground-attack planes in your small group are able to kill the ack, and WF the town quickly (say under 2 minutes maximum)
3) if detected, too few/unskilled enemies up to challenge you, or they up too late to stop the capture
If any of those conditions aren't met, the attack is almost certian to fail.
