I guess this could be programmed with Scheme,
But there is a possibility to use regular expressions in a text editor or wordprocessor to
extract sequentially the 1st then the 2nd voice.

Replace string
Left part of the chords
<([^\s]+)\s[^\s]+>([0-9\.]*)
\1\2
Right part of the chords
<[^\s]+\s([^\s>]+)>([0-9\.]*) \1\2
This regex extract the left part in <aaa bbb> and output it in the variable 1 (the first
part in parenthesis), extract the duration after the chord (digits and dots) to add it in
variable 2 (second group in parenthesis), Output string is \1\2 followed by a space.
Copy the sequence and select it, then one choses replace all on the selection.
Short explanation
* \s means space
* [^\s]+ means one or more characters which are not spaces
* [0-9\.] means 0 or more characters which are digits or a dot.
* (...) select a part as a variable for the output
An example I tried:
<c, e>4 <d f>4. <e g>8 <c c'>2
is transformed into
c,4 d4. e8 c2
then into
e4 f4. g8 c'2

Maybe Frescobaldi has a function/script that does this?
Perhaps this is a job for python-ly?
