Hi John,
Whilst ESA medical reports are now commonly used as evidence for DLA, it is much less common for it to work the other way round.
This is probably because the majority of medical reports for DLA are written by hand, so not available to a different decision maker with a few clicks of a mouse, as ESA85s are.
But in the end, only you can decide whether it is worth making an application - though from what you say it does sound like you have possible entitlement to an award of DLA.
Good luck,
Steve
