I’d suggest that you also take a look at the way the 80/20 program from RDNT is handling fees/incentives.
Instead of receiving laddered BAL grant, their pool is being considered as a core pool and has 0.5% fees. As a result, all of the swap fees are directed as bribes instead of paid to veBAL holders directly leading to votes.
In the first round the Radiant pool had well over 100k USD in bribs paid out to their pool from collected fees across the balancer and aura markets on hidden hands. POL can be used to earn BAL and AURA from those rewards which can then be locked to achieve the same effect as the grant.
From what I have seen so far, this format of incentivising an 80/20 pool seems both more beneficial to the DAO and less complex from a governance perspective (doesn’t require a grant). At best your locker would stake the tokens in AURA to farm max rewards. A single recipient gauge rules out AURA rewards as veBAL boost is no longer in effect.
See here for how this was handled in governance. We probably still need to write this up more. Get in touch with @solarcurve or myself if you want some help thinking about it.
