Add the VHF module to the system attached separately to the mast but rotated so it is perpendicular to the direction of La Jolla. Adjust as needed. See below.
What this does is create a UHF antenna that is bi-directional north/south and a bidirectional VHF antenna that is NW/SE, both with an effective beamwidth of 65-70°.
You do not need nor should you use any amplifiers, they are unlikely to help and are far more likely to cause new problems.
One complication that I do see is related to your desire to provide Mexican programming for your wife's viewing. Estrella TV is carried in the SD area on KSDX-LD, a low power channel 9 signal from Mt San Miguel. Because of this, you'll probably need to see if you can readjust the VHF dipole so it's facing more towards the north or even more easterly to see if you can cover both VHF transmitter sites.
If you have problems with reception of VHF channels, the first thing to do would be to install an FM filter.

Messed around with aiming the antenna for several hours last night, and strangely the best results I got was by aiming it at 145 deg. I'm guessing that's because mostly everything to the north is line-of-sight (I can see the towers from my window), and I have a small hill and some houses to the south. Strangely though, while I can pull in real channel 32 and 34 (XEWT and XHAS), I can't get 28 (XHJK). Those all appear to be in the same location. Also KBNT won't come in, but KGTV and KFMB are very strong. Any ideas?
