i wouldn't, keep playing in dos-box, to me everything works fine, speed is not processor related (the game is that fast). playing in dos-box gives you the advantage of a full joystick control, by mapping keys to your joystick.
did you tried FFED3D?
listed below my .conf file for frontier/ffe, it's ment to use with dos-box 0.73

///////////////////////////////////////////////////////////////////////////////////////
you have to edit this to compare to your system of course (capture location, screen resolution)
start it with a command file like this (frontier.bat)
///////////////////////////////////////////////////////////////////////////////////////
start dosbox \game\frontier.exe -conf front.conf -noconsole -exit
exit
///////////////////////////////////////////////////////////////////////////////////////
all files have to be in your frontier directory together with dos-box.exe and it's dll's (i.e. "D:\games\frontier\game\"; dosbox and files goes to "frontier")
tip: you can even install your game like you did from floppy or CD with dos-box.
