This is basicly in line with a bitcoin strategy ... so to speak... back in the days when terra/ust was around there was idea to buy btc as a colateral for hbd... it didnt materialize .... the tricky part has always been the security of the funds and who will hold the keys.
My feedback is to implent a simple thing, buying btc over a four years period, not trying to time and trade, buy it with all the funds. But first think deep about funds managment and security and try to speak with the top dogs and convince them about the security and decentralization of the wallet managment.
Noted, although not my style though. this can be disclosed over time with every-year roadmap + monthly checkpoints
