Can two antennas be spliced together to pull it into one line without an A/B switch? Or is that impossible?
A rotator is a valid option. When adding a second TV, some folks have opted to install a second antenna dedicated to the second TV. When there are stations scattered around the compass, this is one of several options. Look into the CM-7000 set-top-converter... it's getting a bit hard to find but it was one of the few STB's that integrated rotator control. (When I checked the link, Channel Master indicated that the unit is out of stock. If you can find one for sale, it integrates with the CM9521 rotator.)

The Channel Master CM9521 rotator & remote is a complete option by itself.

You can try an omni... but I expect you will be disappointed with the results. The signals in the red section of your report would be unreliable if received at all.

Combining two or more directional antennas almost always yields results similar or worse to that of the omni. Exceptions to this are the result of blind luck or excellent professional engineering backed by skilled installation, measurement and tuning using commercial grade parts and test equipment. (A cable TV head-end for example.)

A premium setup using a rotator would be a roof mounted Winegard HD7698P antenna, an Antennas Direct CPA-19 preamp and a rotator.
