You're aware that two weeks * 40 hours/week * $1000/hour = $80 000 (plus HSMs and ongoing costs imposed by additional security), and that the Bitcoin breaches we've heard of so far cost $100 000 - 300 000? The level of security you're proposing seems excessive.
(Also, their "team" page seems to list one person. It's very hard to make XofY security work in really small organizations.)
All that said, Bitcoin security is amateur hour, and you're right that there's a lot they could learn from people who have solved such problems before.
Shouldn't it worry (terrify?) you that a small group of two or three people could coordinate with each other and abscond with your money? Isn't the fact that $80,000 worth of consulting costs is considered an investment too large to consider making also a pretty big red flag?
<snark>Meh, this is Bitcoin. If it takes more than one bored teenager with some off-the-shelf SQL injection tools to abscond with my money, that's better than expected.</snark>
More seriously, the threats faced by a real bank are more serious than the threats faced by a minor Bitcoin operation.
That said, there's no way I'm trusting any significant amount of money to any of these outfits.
