I'm wondering, if the designer didn't want to duct the air anywhere else,
would the front panel have a much larger vent?


Plan A.
What I'm thinking about is cutting a large hole in that big face panel
and covering it with a guard wire to protect the HX from fingers etc.

Plan B, would be to cut some round holes and install some muffin fans on the front panel, to increase the air flow..

Would any of this help speed up recovery time?

Edit:
One experiment I conducted on that vent, was to tape a long flat rectangle of CoroPlas, a 'door' or hatch on top of the vent.
The idea was to gravity-close the vent when the A7 was off..
The little flap-hatch would be pushed up (by air pressure) when the A7 was running,
and then drop down and close the vent when the A7 was off.

The problem that I saw, was very light weight of the flap-hatch
was too heavy for the air flow to push it up out of the way..
I'm thinking wow, this is very low air flow. It would only open about 1/2".

So, maybe an air-pulling fan out front??

Well, you have changed the whole dynamics of the coil with that hose on it. I'll bet there won't be enough air flow and you will get a freeze up. You will need to get the air flow back close to its original spec.
