What about clans with no current P/R League? Is there any way for them to still participate?

Create a clan p/r league

or any other competitions to define your representatives
to define 3 players you could

make a double elimination tourney also

single elimination and let both 3rd play a decision game

round robin with all interested and take the top 3

make a FFA and chose the last 3

chose the top 3 players of your clan on the 1v1 ladder at a previously fixed date

chose the top 3 players of your clan on the MDL at a previously fixed date

throw dices

if there is any internal clan competition, then there should be a way to define some representatives with it

.. give your imagination a free run :)
