@mikej460 You could probably do it with an Alaskan mill and that smaller saw. I sometimes use my tiddler saw and a 14" bar for re-sawing.
I bought the larger mill because I was milling for the house repairs and have milled something like 70 tonnes on it so far, so it has paid for itself many times over.
I'm a bit fussy with milling for timber repairs and I tried to get a mill to do it for me, but they struggled, as they were set up for automation and had to manually mill the stuff, which slowed them down.
If you look at a commercial mill set up, they are very specific about what they take and like to mill at speed to cover their considerable costs.
I have one of these too....
