Son, when I proposed the series configuration I thought that you have already have an amp and would like to convert it to single plate configuration. However, if you “decide to build” then I very much recommend you to go for 6.3V and just to provision extra current in your filament transformer of the transformer secondary.

You do not want to lose an action to go full power with your 6C33C, so extra current will help of you run both filaments in parallel. Parallel configuration has, in my view, benefits that it might be shielded. I presume you run AC on filaments and if you use series connection then there is no way to twist the wires and if you do run the twisted pairs with series configuration then it will be longer wire and not elegant. With parallel configuration the AC supply to filament wires are much short and much more accurate...
