KOAM and KHQA are both strong enough co-channel interference sources to present a problem. Side by side stacking can produce a more narrow horizontal beam-width which would be desirable, as a means of rejecting the interfering signals.
Use of a reversed splitter (CC7870) as a combiner comes at the cost of about 3 dB. You still get the modified beam-width though. A pair of Antennacraft Y10713 with their 300 ohm outputs would lend themselves to combining via 1/4 wave long sections of 450 ohm ladder line, thus less combining loss.
I think your consideration of the combo antennas is a viable option also.
I think the solution is going to be a combination of gain and interference rejection.

Thank you for the thoughtful reply. Yes, they are stacked vertically, not horizontally. Not sure a horizontal coupling is going to hold well up there. I did not realize I was losing around 3db of gain with the coupler. The Winegard Tech told me I would actually lose no signal when coupling in this manner. That may be the problem then.
