You will probably find that gain is too high with what you have drawn up. There are lower mu tubes you could use up front that also have lower Gm, so they'll be less fussy about layout.
The 1uF interstage coupling cap is an odd choice unless you have a very specific part in mind that you'd like to use. The grid leak after the 1uF cap would be ~25K or so for decent LF rolloff, but that 25K resistance will defeat the use of the plate choke in the first stage. 0.047uF/500K would be my recommendation for that section.
What you have drawn isn't a White CF, though I don't believe it has to be for what you're looking for. Here's a basic diagram of the White CF from our friend Broskie:
You could simply put a low gain triode ahead of the 6C41 and load the 6C41 with a constant current source or a plate choke as the load. Yes, 32V/180mA is pretty spicy in terms of dissipation, but it's doable.
If we roll all that up into something you could build very easily, it might look like a CCS loaded 12BH7 with maybe 65V on the plate running off a 125V supply and the 6C41 could run off the same supply and be cap coupled to the 12BH7. With the ~25V or so on the cathode of the 6C41 running 100V P-K/180mA IP, you have plenty of compliance to use a CCS. This would get you to ~60 ohms of output impedance. If you wanted to go lower, you could put a little feedback around the amp.
Use the huge poly caps. You have them and they are better off in an amp than sitting in a box somewhere in storage.
