I am very, very happy to hear to this!

Delay time and feedback would be my vote for delay parameters. Price
sounds fine by me, lower is always better, but 400 doesn't sound too
high.

I think keeping the feature set to things that make since ∗within∗ the
modular signal chain as opposed to pre/post processing is pretty
important. There are plenty of other fx processors to handle those
tasks. It doesn't need a reverb, for example. It also shouldn't try to
replace your guitar looper, there are better tools for that.
Most importantly: This delay must never, ever, ever, ever digitally pop
or clip. Ever. At all. No matter how it's abused.
The feedback should be literal, that is, the final output stage of the
looper should have two outs and two inputs. To do feedback you take one
output, route it back into the CV controlled input and it's
remixed/limited/filtered with the main single. This allows for doing
things to the feedback signal in unusual ways, like passing it through
a '440 on an LFO'd cutoff . There is an ocean of sounds to be made from
screwing around with the feedback before it gets pushed back into the
delay line.
Changes to delay time should not clip. Play with the delay on the
access virus for an example of a very nice delay. Delay time should be
CV controllable, and sync-able. In other words, a re-trigger signal
for the delay. One should be able to sync delay to an LFO or pulse
wave, etc. Fun sampling like effects could be done with this.
There's certainly room for more than one kind of delay in the MOTM line
too ;)
