I too am looking to switch a DC load, and intend to replace the triacs with NPN transistors, or FETs seems very straightforward.
The problem has been in finding a transistor that suits – the gate for the triac is on the right side of the SOT-223 package, whereas it seems for all transistors, the gate or base is on left side of the package. So no easy ‘drop in’ replacement here!
Has anyone found an straight forward method for doing this swap?

Many thanks!
