Don't see the point in conferences, were not a huge nation that needs to reduce travel time, and there's absolutely nothing wrong with have separate leagues with promotion and relegation. Meritocracy is always preferable to dilution.
I'll just copy/paste my thoughts from the last thread on this, from about a month ago.
IMO, decrease the Prem to 10 teams, 5 get EPRC places.
Probably shrink the champ to 10 (we can sustain a good 20 fully pro clubs IMO)
Increase promo/release to the Championship to 1 automatic and another play off.
Ring-fence the top two leagues (with specific criteria to eject underperformers or include ambitious semi-pro.s)
MSCs for both leagues, but looser than the current, but with additional requirements for admin etc. Same salary cap for both.
TV deal is for both leagues.
RFU academies for all.
Expand the AWC, by adding the champ teams. 6 pools of 4, orthodox fixture list; knock-out stages to include cup, plate and shield, so that everyone gets KO experience*. Players only eligible if they played less than X minutes in the previous season.
This gives us 6 pool + 3 KO weekends to fit into the 10 week international window. We've bought that by reducing the league by 4 weekends and helped player welfare with that game time limit for the domestic cup - I'd also have a maximum number of minutes for every player anyway.
Clubs go from 22+2, 6+3, 4+2 (32-39) matches to 18+2, 6+3, 6+3* (31-38) matches, so the loss of 1 home game, higher quality in the league, greater variety of opposition, especially for the less experienced players, higher quality Championship, with a chance of giant slaying in the cup, and a guarantee that everyone gets a QF*.
Increasing the quality of the champ, along with inclusion in the TV deal (and the direct cash and subsequent sponsorship and growth opportunities), increased promotion opportunities, giant-slayi g options, and that ring-fence meams that this shouldn't be too much a case of turkeys voting for Christmas.
For the champ teams, without European rugby, you could argue that theyd be lacking match numbers. You could also argue that this is better for player welfare, allows them to rest ahead of their giant-slaying opportunities, and allow for smaller squads... But I suspect that wouldn't fly, and we'd need to reinstate the B&I cup or something.
Alternatively, increase the champ to 14 (just the 2 dropping down being added), which negates that league, but would mean throwing the Welsh out of the domestic cup (oh well, nevermind), but does count against improving the quality of the champ. I vacilate on this each time I think about it, and I guess it would ultimately depend on how many champ clubs want to go fully pro and have (reduced) MSCs applied.
Of course, you could get a situation where, too many champ clubs would choose not to go fully pro; in which case I'd argue for the RFU getting involved and "assisting" 1-3 clubs in union-poor areas, say Carlisle, Blackburn or Canterbury
