Yes. That's what I have in mind. The 2 of 3 with CASA has been great but having one key at home and a recovery with yourselves available after only 1 week puts us at risk with determined attackers willing to wait it out. I guess timelocks are great for the pure self custody route for soomeone who is already well versed in Bitcoin. I run my own node and can connect my wallet to it. Meanwhile I don't want any key at home and timelocks allow me to cater for a lost key and create a 3rd, independant path for inheritance. Regarding CASA, I was thinking timelocks could make your customer's setup more robust. I remember being on the phone about a year ago with Zach I believe who was suggesting I keep a key at my sister's who lives 2 hours away. I don't think that's nearly enough to deter a $5 wrench attack. At the end of the day we all have different circumstances and options for securing keys.
