Removal of Truvativ adapters on Hope bottom bracket

[beanbag]

I've just bought an XT M770 chainset to replace my worn Truvativ Stylo that came stock on the bike.

The only problem though is I've got a Hope bottom bracket which I don't want to change however it has a Truvativ GXP adapter fixed to one of the bearings to allow for the Stylo crank.



Does anyone have any idea if these can be removed or do I have to buy a new bearing for that side of the bottom bracket? They simply fix to the bearings with a few taps of a hammer but I'm worried the bearings themselves would be damaged when removed.....
