Given the nature of the asset, I think it is a mistake to do this since with relatively little volume it can be manipulated easily 

Don't think this is a economically sound decision to use INTR as vault collateral - I would vote against

However, if you gave Vault holders a pumped yield to take their rewards in vested INTR (so they can't sell immediately) then I would vote AYE

We basically already did this by redirecting 50% of vault rewards to staking. So if you get INTR rewards from your vault you can stake them to "boost" your rewards if you decide to lock them up rather than selling them.

The INTR token’s value depends interlay’s protocol success.
The more bitcoins collateralized on Interlay and the more value has INTR token!

If you use INTR as collateral, you are just fueling a Ponzi scheme and nobody wants that!
Use any token as collateral, but leave INTR alone.
This is my opinion!

Allow INTR to be locked in vaults and give greater rewards for it

Give better rewards for INTR vaults as incentive
