Hey, good one! 
Yes, being able to buy/sell from the DEX LP directly next to the graph would be excellent!
And it would also provide us with a second way to access the DEX: One through the in-wallet DApp, and another through BeamAssets’ web-based interface! 
I think the BEAM DEX needs a frontend Web app page integrated with Beamassets.
Also we should allow this frontend web app interact with Beam web wallet.
That way people doesn’t need to download desktop wallet in order to do privacy swap.
Loving the work you have put into the site… It looks and runs great!
