just pasting this here for now, I'll make a proper writeup of this in the coming days.

The integration part could probably be done by putting both frontends in the same DApp and creating links between the existing windows. See mockups below. No need to change anything in the smart contracts.

The DEX part would need to know if a reward already exist ("get reward"). And the accumulator part would need to know what pool has called it (to only show the rewards for that AMML only, and to manage the 'back' link). I don't think we would need more interaction than that between the two sides.

Thank you for the quick mockup
