With a saw like that, I'd consider a quick lash up as per Carl Holmgren, no need to make a latch for such experimentation,
as you might choose to weld up something after that.
The lash up would likely be appreciated, as it might take a bit of head scratching concerning the location of swivel casters, which can dip an end of the machine when swivel casters at maximum swing. as this timeless design of lifting mechanism can be troublesome if wheels too close to the centre.

Worth a look at those designs, as you won't find better, if you can make it work without too much hickups.
Saying that, for seemingly such a sought after machine, guessing there's a theme of OWWM which yer going for,
then it could/WILL be made work,
well...that would be the case for myself, as my own bandsaw base just looks annoying/stupid to me now, after spoiling myself.

All the best
Tom
