This won't work. The attenuation of the splitters will exceed any
potential gain of adding feeds together; the attenuation of the
splitters will almost certainly stop the control signals from the
digibox controlling the LNB properly, and you're exceedingly unlikely
to get the phasing of the signals to add. At best you're signal will
be worse than before and at worst the digibox won't work at all.

I would check the dish alignment first, then try and find a site for
the dish that is not obstructed by trees. Even with a larger dish you
are likely to have problems unless you have clear line of sight to the
satellite.
