There's nothing about geosync orbit that would help with the tree/canyon effect. Satellites directly overhead contribute the least to horizontal positioning - essentially only helping to establish the "true" clock value but not 2D position.
Multi-constellation tracking can be helpful, simply because there are more satellites to use.

Real world tests show that it works better than just using more constellations in lower orbits. https://www.ion.org/publications/abstract.cfm?articleID=9679 https://www.ion.org/publications/abstract.cfm?articleID=9679
