Assuming we implement this feature in the BTS / USD market and voters approve workers funding this at a rate of 2.5 BTS / sec (50% of allowed dilution) and the internal exchange had $100,000 of daily volume then users trading on the internal exchange would see a 1% more than they would get by trading off chain. If daily volume was $50,000 then they would see a 2% profit over doing the same trades off-chain. The impact of this should be a major influx of new traders who can make more money trading on the internal exchange than the external exchange. This added liquidity will dramatically tighten the USD / BTS peg and give shorters much more confidence. 
That's $365 000 a year of dilution.  That could be  

 on $7 500 000 worth of BitUSD. 
Even with a lot of yield harvesting that would rapidly make BTS the undisputed Crypto USD market leader. 
Uphold: $2 Million 
Tether: $1.4 Million 
Nubits: $0.76 Million 
BitUSD: $0.098 Million 
Liquidity is already guaranteed for the longs via forced settlement & with that much in circulation, shorts should have confidence there will be sufficient amounts for sale when they need them. 
What about at least putting 1/2 of the proposed dilution towards BitUSD yield? That way you would rapidly increase the BitUSD CAP to >$3.5 million dollars while significantly increasing volume at the same time? 
(I would also decrease forced settlement to 98/99%.)
