Sure. Find attached 4 patches.
In order of application, they are:
1) browse-url-rm-grail.patch; this patch removes the Grail code. I understand it's nice to have compatibility with lots of browsers so people can use their favorites, but browse-url.el takes it a bit far by including support for browsers that haven't been updated in years or decades. Grail in particular hasn't been updated since something like 1999, doesn't run any more (I found one 2007 post complaining that the Sourceforge downloads had multiple significant and fatal errors), and probably no one uses.
2) browse-url-rm-ixi-mosaic.patch; ditto. I couldn't even find where to get IXI's version of Mosaic. It apparently got bought or released by SCO in 1995; besides echoes from browse-url.el's inclusion of it, I could find little to nothing in Google. I think it's safe to say that if anyone is still using it, they probably aren't in a position to be using Emacs 23 and up.
3) browse-url-rm-mmm.patch; like above. Last update in 1997 or so. The libraries this O'Caml browser uses seem to be similarly outdated.
4) browse-url-rm-generalize-and-add-text-browsers.patch; this is the important one. What I did was rename all the Lynx variables to text, pull the lynx specific parts out of browse-url-lynx-emacs, and made it more general. This was nice because it made it easier to add browse-url-links-emacs, browse-url-links2-emacs, etc. I've only lightly tested it, but it seems to work.

Browse-url.el offers a neat function browse-url-lynx-emacs which opens up a Lynx browser within the current Emacs frame; this is very nice for binding so you can quickly follows hyperlinks and works very will with documentation and stuff like email in Gnus.
But I don't use Lynx, don't have it installed; looking through the source, there doesn't seem to be anything truly Lynx specific about it, and in fact, just substituting 'elinks' for 'lynx' (and removing one or two superfluous lines) seems to work fine.
Even better would be a general function which just runs a specified text browser (since there are a lot more than just ELinks and Lynx out there). It wouldn't be terribly difficult to do - add a parameter to it, replace browse-url-lynx-emacs with a specialization of the generalization and you are more or less done (although I don't know how one would handle the various variables tweaking browse-url-lynx-emacs); I've attached a sort of example.
