I would hazard a guess Channel 4 were interested, as they seem to like Irish comedy, just look at the huge success of Father Ted and Derry Girls - if Mrs Brown's Boy had have been made for Channel 4, I wonder if the decline would have been slower and probably Channel 4 ending it around after a few years.

Strongly doubt it would be Channel 4, it doesn't fit into their brand whatsoever and has no similarity to either of the shows you mentioned beyond the fact they are Irish.
