Something that you can do is something like we have here in Sweden - we have a district setup with some places for each district that is proportionally distributed.

But that create inefficiencies as that heavily favour some parties. So we have a chunk of undistricted delegates that are given out to even out the overall proportionality. This get you pretty good results as long as the amount of parties stay within reasonable boundaries[].

[] Which they of course haven't - we currently have 8 parties in the Riksdag.
