Maybe. Or maybe you'd see increased participation, especially from lower-tiered players who, like the OP, feel that they have no chance to win prizes under the current scenario.
Sorry, for some reason I thought you meant a flat entry fee. A couple of things before I'm out of this as I feel I've said enough and am not in the least worried wgt will do anything along the lines you suggest.
What you are suggesting at the top level is making it a tiered competition. The tiered monthly has much better prizes and costs 200c to enter but people are not daft enough to think they are going to beat the best scoring players. There were 48 that finished last months TC one and 55 at champ. I wouldn't pay 250c to enter what you propose, I wouldn't pay 100c.
There are specialists at the coin/apparel game too and perhaps that's among the reasons that some of the best non-apparel players are found in the Veteran Showdown.
Once again on the op, he's a Legend playing in Rookie that wants tiers above him banned from playing there. I don't see a lower tier player being cheated, I see someone who wants things all his own way and I don't think he'd thank you for making him play in Veteran.
The point on TM's and TL being off the same tees is that you'd force the TM's to that and that's unfair whichever tees they are. Any TM in Veteran now at least has chosen to enter there.
Lol @ Ana; Of course he could get the coins needed but he'd miss a dozen bracket rounds spending the time doing it, that'd be expensive ;-)
