You don't delete them arbitrarily. Have a look at the
Sun-Ext{A,B}.ttf fonts, either with Fontforge itself (requires a *LOT*
of memory) or with gfontview (which is very fast, and shows plane per
plane; switch anti-alias on), and you'll see what I mean.
Now it's pretty simple why they get the same name: you gave "sunext"
as one of the arguments of the fontforge command when processing both
fonts. Usually, when you compile two fonts, each font should have its
own name, obviously. But apparently Sun Haifeng decided to split one
font into two fonts.
Fonts A and B have a 00 plane, but A has a lot of other scripts
besides Chinese. Just have a look at it with gfontview or fontforge
if you don't believe me. The B font only has a handful of ASCII
characters and the rest are Chinese characters from Extension B.
So keep the 00 plane of font A, and remove the one from font B.

LoL! That's certainly *not* a deficiency of subfonts.pe. If there's
one deficiency, then it would be Sun Haifeng's fonts since it is split
into two fonts. Normally TrueType Fonts only have *one* TTF (there
can be more fonts for the different variants). So there's nothing
wrong with the Fontforge script. Why is deleting the 00 plane of the
B font so problematic for you? o_O?
I didn't try to convert it yet to the GBK encoding. You can try to
create subfonts using the GBK encoding yourself. You might also try
to use "virtual fonts": they use the Unicode fonts but use the GBK
codes.
Have a look at the uni2sfd.pl Perl file. For more information, view
the Perl files and have a look at the files in doc/.

作者:晏殊（９９１－１０５５）
油壁香車不再逢，峽云無跡任西東。
梨花院落溶溶月，柳絮池塘淡淡風。
几日寂寥傷酒后，一番蕭瑟禁煙中。
魚書欲寄何由達，水遠山長處處同。
