Threshold
just for a begining, after diverses criteras of valuations to be determined by specialists seem necessary and suggest a temporality of try at verification all the year or by 6 or 3 month, but its optimitic and a good first step try.
And is a few amount of dot.
Because 4.96* 365 = 1810/YEARS 12.55 * 365 = 4580.75/YEARS so if estimate the minimum cost of Dot at 6 and 8 dollars in bear is correct because between 1810* 6 = 10860 dollars or 14480 * 8 and 4580.75 *6 = 27480 dollars and 36640 dollars * 8.
I do not take into account the future inflation effect about Agile Coretime update nor a non-sustainable effect accentuated by a bull market climax.
If stay thus, is the responsability of dev to convert if increase or decrease value of dot however. So manage yourself our budget.
Is not bad proposition.

I am not sure to understand the intention correctly. You mention that this could be a replacement for crowd-loans to gather project funding - yes. But how does it relate to treasury grants?
Getting a nomination-based % of inflation is not a very strong promise for grantees. I think in this case, it would still be better to have Treasury instalments, that pays out grants in chunks on a monthly basis. This still gives the Treasury the possibility to intervene on non-delivering projects.
Also what is the priority on this? Expected timeline? How important do the voters think this feature is on a scale 1/10?
