Go with your original plan for vertical stacking. Try 5' anyway, it might work OK.

Few low band antennas have rear mount options.

Let's see; 1/2 wavelength on channel 6 is 5.8 feet. On channel 2 that's 8.6'. That's a bare minimum for modest interaction between the antennas. The real question is can you live with some coupling...

If you can center the drill in the center of the egg shaped holes you'll end up with a better repair. The straps you have installed may get in the way of that goal.

I found your old link to a radar report. Your VHF antenna should be aimed at 341 to pick up WHTM. Your DB-8e needs to be split in two directions; 351 and 64 degrees.

Should you opt for the clamshell reinforcement, the normal way to protect the patch from water entry and possible ice damage is to seal the seams with silicone caulk.

Those are grade 5 coarse threaded bolts. Note that older Rohn 25 was shipped with NF threads. The thread pitch doesn't change the strength.

By opposite directions I meant that the two antennas cannot be aimed at each other. The reflector screens of the antenna in front will block the signal from reaching the second antenna.
