Production Switchers

I want to get some feedback on implementing a couple of squeezebacks.  I'm working with a Carbonite and have the squeezeback built on ME 1 and ME 2 is my P/P.  

1. Perform CC 1 which sets two sources of keyers in ME 1
2. Set BG of ME 2 to the highest keyer from ME 1 (DSK 2 in this case) 
3. Take ME 1 on ME 2 BG so we are linked to the same source on both MEs.  
4. Perform CC 2 to squeeze back
5. Grow Right or Left Full on ME 1
6. Take same source as ME 1 BG, on ME 2 BG to link back to ME 2 on PP.  

Is this the best way to do this?  It seems like I am limited by ME follows because I cannot set ME 1 DSK 1 source, to ME 2 BG, which would solve all my issues since it would follow the source I needed.
