My primary concern is to have enough low noise gain with the OTA HD signals
If you are concerned about distributing a signal around the home under conditions of marginal signal in a deep fringe environment...separate runs are best. diplexing adds a loss at insertion and then again at separation almost equivalent to a 2 way splitter at either end.

try the diplexing process without extra amplification first (since you are already using a mast mounted amp) then add your distribution amp to see if there is improvement. terminate the unused ports.

distribution amps are not necessary under many conditions if you installed a mast mounted preamp at the antenna. the extra losses associated with diplexing in your case may make a distribution amp necessary.

first install without the distribution amp. if the signal needs an extra boost then add one and compare.

If you are then not satisfied , extra runs should improve the situation.
