First, we need to identify what the trouble is, then you see if you can manage it, and if not, what needs to change to address it; with steps that equate solutions to actions with more than wishful thinking.
Personally, I'm not seeing the steps between "we kill 2 clubs (including one of the best supported) and have franchises" gets us to "there's more money in the game" there just seems to be some detail in there that's missing.
Please note, I'm not particularly opposed to franchises as a matter of principal - though I am opposed to killing what we have just for funsies.
For that matter, I'm not particularly convinced that "the pro game (in England) is in trouble"
2 years ago, the average turnover for the 10 current clubs was ~£20M each.
The salary cap is £5.5M; with a marquee player, coaches, and a separate academy cap on top of that.
I'm pretty sure there's some cost-savings to be found in that intervening £14.5M
Sale can run a club on a turnover of £11.7M and an average gate of 5,385 - and spend £12.1M (with 20 members of staff in "Sales and Admin")
You've then got a club like Exeter, on as turnover of £25.7M and an average gate of 10,390 - and spend £29.7M (with 198 members of staff in "Sales and Admin")
I'm pretty sure that Exeter pay that extra £17.6M p.a. because they choose to, rather than because the extra spend is 100% essential to run a professional rugby club.
It looks to me, more like the problem isn't "there isn't enough money in the game" as it is "clubs are spending the money the way their wealthy owners (or board members) want it spent, rather than necessarily in the best financial interests of the club".
So, for solutions
A] What problem are you trying to address?
B] What is the proposed solution to that problem?
C] How does B] go about addressing A]?
D] What are the potential forseeable side effects of B]?
From what I can tell, reading the last 50 posts, we don't even know what A] is
