Sure - A splitter IS a combiner in reverse. No worries about feedline 
lengths.

In the analog days, it was preferable to use a combiner with some sort
of frequency tuning depending on the particular channels you were trying
to access. You might use a diplexer, or a single channel inserter, or
multiport single channel filters, etc. The intent being to minimize
multipath interference from 2 antennas aimed in different directions 
supplying signal for the same channel.

Digital, though not without issues, is much less prone to ghosting
problems, so simple broadband combiners can work well in many or most cases.
