I definitely could! It would probably only add a line to each post-interaction dialog box. Something like this:
> A goblin jumps out of the vase and sneers at you!
> What do you do?
Attack {Strength}
Frighten {Charisma}
Befriend {Charisma}
Trick {Charisma}
Escape {Dexterity}
> Befriend
> You offer the goblin a small snack from your satchel. They cautiously accept and begin nibbling.
> {Roll: 12 vs. 16 -- Success!}
> The goblin yips with joy and tugs your arm towards the vase.
Inside, you see a cache of gemstones worth 50 G.
When you turn to thank the goblin, they are gone.
The results would be a little odd-looking to people familiar with 3e and later editions, though, since I'm using the roll-under-ability-score mechanic from Basic/Expert D&D, instead of the roll-over-difficulty-class mechanic from modern D&D.
