rather than run two new lines for two new pieces of equipment, i would
like to run just one line and share the new outlet given that i would
never need to use the two pieces of equipment at the same time.

one of the pieces of equipment i want to hook up is rated as 1p, 240v,
47a and came with a 6-50 plug. the other piece of equipment is rated
as 1p, 230v, 28a and came with a 6-30 plug.

my plan is to run a dedicated 50a line which would accommodate the 47a
(6-50 plug) piece of equipment. i then want to change the 28a piece of
equipment's plug from 6-30 to 6-50 so that it will also fit into the
new 6-50 outlet.

would this create a hazard and/or damage my 28a piece of equipment?

AS long as you wired the plug correctly you will be fine. The device will
only use the current it needs.
