It's not at all an optimal design choice and it would seem essentially
trivial to make the lags machine bolts, ideally w/ the plate also on
the back side.

One thing to consider is that with lag bolts you have to drive the entire
bolt in. At 4" long, that's a lot of driving to do. Conversely, with
machine bolts (such as carriage bolts) all you've got to do is drill a
through hole and attach the nut.

Just something to think about as you get to building. On my ice rink last
year I switched after the second lag bolt to carriage bolts and got the
thing assembled.
