gen7 redesign like a gen 1.4b

thinking of a generation 7 1.4.1 b differences wanted 2 extruder one hot end support (a Bowden-y design).
servo support for mechanical z-probe.

two fan headers one always on one switched

and support for reprap discount smart display with sd card.

would also prefer to breakout the i2c header for support for realtime clock if it's ever supported in marlin and possibly other things.
any of you have any input because the gen7 1.3.1 has been quite reliable but I think I really need dual extruder support now and
the extra 4 MHz would come in handy.
any and all suggestions on pin assignments would be welcome.

Best of luck. Traumflug was the only Gen7 developer active and seemingly ragequit from these forums a while back when people were questioning his stance on continuing to use the now discontinued LPC DIP chip iirc.

There's simply not much to talk about Gen7, because it works so flawlessly. And of course I have these fast and DIY-friendly ARM chips in stock.
