Our company faced a similar decision when we rebranded our production company. Trying to find available domains to support the rest of the branding was challenging.
In the end we made the decision to move forward with a .be domain. We did purchase a "not-very-good" .com as backup in case at some time in the future we couldn't use .be any more.
(Not to be self promotional -- but the company is Busy Worker Bee (busyworker.be) and we use the bee, hive, honey, blah blah metaphor in our sales and marketing)
We have found that our clients enjoy it, and it always makes for a nice elevator smile.
Based on this experience I say -- go for it!
