there is an InsertEnter autocommand which is triggered just before
Insert mode, Replace mode, or Virtual Replace mode starts. The actual
mode is indicated by the v:insertmode variable which contains 'i', 'r',
or 'v', respectively.

I can't test this due to lack of access to a real terminal, but

if &term =~ "xterm"
autocmd InsertEnter *
\ if v:insertmode == 'i'
\ " blinking vertical bar
\ let &t_SI = "\<Esc>[5 q"
\ elseif v:insertmode == 'r' || v:insertmode == 'v'
\ " blinking underscore
\ let &t_SI = "<Switch Cursor to Underscore Here>"
\ endif
" blinking block
let &t_EI .= "\<Esc>[1 q"
endif

should get you somewhere.

Note that I removed the dot from the assignments to t_SI. Otherwise the
terminal sequence would grow whenever you enter Insert or Replace mode.
If t_SI is really initialized with some value that you want to append
to, you will have to remove the part that was appended in previous
invocations of the InsertEnter autocommand -- or save the original value
of t_SI before you define the autocommand and rebuild the complete
sequence every time from the stored value and the sequence used above.

The InsertEnter autocommand is not triggered when replacing single
characters with <r>, but you can always use a mapping:

nnoremap r :let &t_SI = "<Switch Cursor to Underscore Here>"<cr>r
