I ran into a similar problem when I resawed a 2×4 to 1/4 & 3/8 strips, jointing, and gluing to get panels for my 2×4 project… 3×5 box. This is what I did:
Start like you did EXCEPT:
1. Add another clamp in the middle.
2. Have Spring clamps on each side to hold ends together horizontally; over each glue point.
3. Put a piece of scrap 1×6 & 2×4 on top & in the middle (protected with waxed paper) (same direction as the clamps, but on Top) then pile on some concrete blocks to make sure everything stayed FLAT!
Worked like a charm!
Note: I tried much like your setup… would NOT stay FLAT... had to cut apart on the seams and REGLUE as done above.
