You can.
I do not quite understand, what you want to do (all my US-ASCII keyboards
don't have an 'erase' key), but perhaps the following example of two
example entries to /usr/share/misc/keycap.pcvt might illustrate the way to
go:
x1|BS1|map backspace key to <DEL> (0x7f), SHIFT-BS and CTRL-BS to <BS> (0x08) :\
:K15=\177:S15=\010:C15=\010:
x2|BS2|map backspace key to <BS> (0x08), SHIFT-BS and CTRL-BS to <DEL> (0x7f) :\
:K15=\010:S15=\177:C15=\177:

Some years ago, when the keyboards where quite a bit more expensive than
today, one could get sort of a technical reference manual with all the
machines (i have a good graphical representation from an HP Vectra tech ref
manual and from a Kyocera tech ref manual and several more) that were sold.
A not so good representation can be found in: The Programmers PC Source Book,
by Tom Hogan, Microsoft Press (mine is 2nd ed. 1991) on page 7-18 and 7-19.

Ha ! Finally ! :-)
I'm waiting ...... :-)
