Well I would say NO.
From my recollection (stopped flying a few months ago!), the destination allternate minima used at the Planning stage assuming that the best approach minima is not available.
So if the airfield has Cat 3 ILS, use Cat 1 minima; ditto (in this case) Cat 1 available, use best non-precision minima (VOR 450ft MDH and about 1000m vis).
In this case it boils down to the surface vis of 7k versus the vv of 300ft. and the MDH of 450ft. I would suggest that you would have little chance of picking up any visual reference at 450ft given the vv (which is effectively the cloudbase) and must be considered.
Now, in flight it is different, as you can then use the ILS minima and nominate it as your alternate.
