Morph Recognition Guide mentions that a spaceflight-capable synthmorph could theoretically do a long-rang stealth mission by aiming at its target, burning some fuel, and letting momentum carry it there over a period of months.

Would it work better if you launched it instead of having it launch itself? Could you camouflage it as a derelict or an asteroid?
