OK, I'll take a shot....
First, I agree with Chris in keeping the second trunk and working/wiring foliage over..
I also agree, from experience, about removing roots on these killing live tree/branches directly above clear to the top of the tree( ditto with Arborvitea).
When I first looked at this thread today I immediately thought the back view shown was a better choice for the front ( Ala Ricks opinion) . It's hard to tell in the photo but the rootage looks nicer there and I think a slight 'roll' of the top would hide those smaller roots (a dead one too it appears) and MIGHT help hide that long dropping root a bit IF the top branching still looks pretty good after a slight roll towards the EXISTING front to show a better front from the now-rear.
Also when I first looked I thought "two-line semi-cascade" as in BNuts virtual, but, it is still just virtual and I feel you'd kill it getting it in that pot, or similar pot, by tilting that much. Just lay a straight edge on the picture and tilt the tree enough to match the virtual and the entire rootbase is uncovered and WON'T look like the virt rootbase which pretty much looks like it does BEFORE tilted!
The solution...to me...Tilt the tree as in the virt. Keep smaller trunk. Use back as front to improve rootage and roll slightly to hid the longer root/smaller roots an ....most important. Put it in a scoop pot to eliminate the problem of exposing the rootbase.
Here are a couple shots I found quickly to show what I mean.
