I don't think it's odd - many guests do a split stay, so this wouldn't be so different.
Do you have a studio or 1 bedroom at WVL? We stayed in a studio and liked it better than the Lodge. The room was larger, the Villa lobby so beautiful (we were there when it was decorated for the holidays), the walk over very peaceful. I was surprised we liked it so much! It is a very easy walk to the main pool (or the Villas have a quiet pool)...you just cut through the Villa lobby, out the back door and walk around the pool which brings you to the lake and main pool. Roaring Forks is just across the way and before the main pool there is a walkway to the water launch docks.
You could always keep checking for a room in the Lodge to open up so you do not have to move. Disney room availiblity changes constantly, so there's a chance it could happen. You could even ask at check-in if you could stay in Lodge, in the same room.
I know it's not fun to change after a couple of nights, but being in the same resort should go very smoothly.
Hope you have a wonderful stay!!
