I'm not sure I understand the last part of this question.  There is nothing
in Xlib that merges multiple events together.

No, you probably don't.  What you probably want is for your application
to execute the "insert" action upon receiving a key event (or a sequence
of key events) matching one of a list of events, where the list of events
includes "any key event with a keycode corresponding to XK_Insert" and
"any key event with the control modifier set and a keycode corresponding
to XK_A".  The Translation Management facility of the Xt Intrinsics are
designed to handle exactly this; see 'X Toolkit Intrinsics - C Language
Interface' chapter 10 and appendix B.

You don't want to use XChangeKeyboardMapping unless you actually remove
a keycap from your keyboard and replace it with a different one.
