I doubt if you'll have an oxidation issue. If the FV hasn't been opened in the 7 weeks, then the top of the beer will have been under a blanket of CO2. Yes, the plastic FV itself is not impervious to gas, and exchange will occur over time - but I'm pretty confident that you'll be fine after just 7 weeks. I don't bottle as much now as I used to - but I rarely ever bottled a beer less than 6 weeks old - usually more, so they were pretty clear when I bottled them. I always used 2 FVs, then transferred to a plastic carboy (even thinner walled!) for a few weeks before bottling. I never noticed any oxidation issues (and I do know what that tastes like).
Personally, I would be more concerned about yeast autolysis as a possible off-flavour. But almost certainly it will be at least drinkable. As Drunkula says, taste it! If it's OK now then it won't get any worse in the bottle.
