We don't want to have various socket boxes dangling from the trees to service multiple strands.
Anyone here have experience with modifying these so i can have one long strand?

DC does not like long runs
that is why edison's DC lost to AC grids
secondly the 50vDC is correct ONLY for the first string
adding more will drop volts too much on both the first and second strings
just buy extension cords to get 110AC to the start of each string
good news is the LED use minimum current so cheap thin wire extensions will work [if they are exterior use rated]
or you could make your own extensions for the 110AC out of thin wire
