how bout juz create another division below conference and move all the reserve team there and juz let them play like its another division

the top 3 move up and the lower 3 on top move down, depends on the quality of the reserve team, in a few years they will be scatter among all the 4 division but they cant go up to premier league.

if the smaller clubs cant win the big clubs reserve then no point they fight to go up and play the big clubs first team right

in this way the small team wont lose their place if they fight for it and the reserve get to play more competitive match.
