That said, it's been stated that solids undergo internal changes over time, and so a living thing transfigured into a solid and back would die within hours.
Hermione was dead when transfigured. Any revival has to already surmount post-mortem decay and the transfiguration damage might not be a significant additional cost.
That may be true, but it may not be, and in transfiguration, you may recall, you do not care to guess. Harry will take every possible avenue to reduce the amount of magical omnipotence he needs to revive Hermione, and he has utterly no clue how much damage will be done with a straight transfiguration, and he has nobody to ask. I don't believe for a minute that the best he came up with thinking about it for 5-6 hours was to simply transfigure her into a ring/rock.
