Ok Landmeister, this is Willies silly solution,
You make the moves exactly as shown offering your opponant to voluntarily to line up with you.
If he/she choses (he/she does not have to line up till after both moves are made) ( EMTLU can happen any time in either player's movement phase) to line up after your two moves then C will no longer be in contact or in a TZ so will no longer have the option to EMTLU.
This will leave 1 in front edge contact with B, A overlaping.
If he/she choses not to line up after your two moves I think ( and this is where it might get tricky ) you can still EMTLU with all your 4 elements as the move phase has not finished.
IMHO the group A-B can EMTLU first, B contacting front corner to front corner contact with 1, A can fall behind B, will line up parallel with B but not in a group with B ( if to line up means just to be Parallel ) or in a group with B ( this would be a stretch as one can not form line to column while initiating combat, and I do not think it is necessary to 'LINE UP' ).
This or these first two EMTLUs do not effect C ( interpenetrate or push in any way ).
As it is still in the Movement phase you can then EMTLU C-D, C as it has contacted 1 will slide into contact with the flank of 1 ( front corner to front corner ), I do not think this will be blocked by D who could as part of a contacting group do it's own EMTLU to pivot on it's front corner ( the one touching C ) just enough to line up parallel with 1 and 2 but not contact as it has not contacted any element.
But and this is a big BUT ( imagine a ten foot high but ), I could be speaking out of my own backside and everything I have said could be completly wrong and an early cold shower could be called upon.
If I was able to draw those diagrams you do it might make my view ( right or wrong ) easier to understand.
I apoligise if I have confused the issue even more than I already have,
William
