Thanks to sleep I got a better idea: \translatefont!

8p.etx contains all this used in OT1, T1, TS1 (and a bit of 8x) that is 
not contained in 8r (but usually available in Unicode encoded TrueType 
fonts) and it is the source for 8p.enc, which is the source for 8p.map, 
which tells ttf2pt1 to excerpt ("cite") only the glyphs at these 
Unicode positions. So the AFM and PFB files are already correctly 
encoded (no real use of 8p.enc yet) -- only some names can be wrong! An 
AFM file can look like this (without the last column):

C 57 ; WX 1000 ; N .notdef ; B 346 172 643 516 ;     √
C 58 ; WX 537 ; N uni00B1 ; B 39 37 498 632 ;        ±
C 59 ; WX 668 ; N uni00D7 ; B 39 98 621 586 ;        ×
C 60 ; WX 537 ; N uni00F7 ; B 85 145 452 539 ;       ÷
C 61 ; WX 691 ; N uni00AC ; B 49 199 643 551 ;       ¬
C 62 ; WX 254 ; N uni2024 ; B 68 0 186 117 ;         ․
C 63 ; WX 1000 ; N .notdef ; B 346 172 643 516 ;     ‥
C 64 ; WX 1000 ; N .notdef ; B 346 172 643 516 ;     ⁰
C 65 ; WX 336 ; N uni00B9 ; B 59 391 275 836 ;       ¹
C 66 ; WX 418 ; N uni00B2 ; B 59 391 359 836 ;       ²
C 67 ; WX 410 ; N uni00B3 ; B 53 391 355 836 ;       ³
C 68 ; WX 402 ; N uni2074 ; B 39 391 365 836 ;       ⁴
C 69 ; WX 1000 ; N .notdef ; B 346 172 643 516 ;     ⁵

And here comes \translatefont: it looks up the C slot number in a 
reference and assigns the name found there to the box measures the 
glyph fits into.

No need for any extra names! Splendid, isn't it?
