We can argue until the cows come home about whether an HST is physically sound to last another twenty years - my own opinion is that the power cars have had an upgrade in recent memory, so should be capable of lasting, but the coaches are going to need a lot of money spent on them (not just for equal access either)...
...however, I think that the significant thing is that after one hundred and fifty comments on this thread, nobody has found a realistic use for large numbers of HSTs post 2020.
Interesting though some of the ideas are (two coach HSTs, 3rd rail shoes on HSTs...), there's not going to be a lot of lines that fit all of these criteria:
IEP and bi-mode will fill most of those "gaps" on the ECML and GWML. Electrification around the WCML (Blackpool, Bolton etc) will see more 125mph tilting trains for the WCML franchise, which will free up most of the twenty/twentyone Voyagers that they have (if anyone wants to split hairs re the "spare" driving cabs), so that they only require some for Chester/Holyhead services...
...electrification of the MML will see the entire fleet of 222s become spare...
...electrification to Hull will see some 180s become spare...
...plus GWML electrification will see the FGW 180s become spare.
So, assuming no more electrification/bi-mode IEP on order, I reckon there'll be enough modern DMUs to run Paddington - Devon/Cornwall and to bolster the Cross Country network (the only real places for HSTs, post IEP) - plus you could run all of the Manchester - Southampton services with EMUs in a few years anyway which means fewer diesels required at XC.
Beyond that... erm... Chiltern's Birmingham services are a possibility for HSTs, but should be very high up the electrification list for CP6 regardless.
The Central Belt - Inverness/ Aberdeen services fit most of the criteria I listed above (fouling the points at Queen Street notwithstanding), but people keep telling me that Scotland would only want post-privatisation DMUs.
Anything else is more about "a couple here, a couple there" (e.g. you could have one or two reserved for the "WAG Express"), but this is tinkering at the margins.
Really, the idea of running large numbers of HSTs post-2020 is that old favourite - a solution in need of a problem. And I really can't see many problems that HSTs are going to be the long term solution for, sorry.

Interesting though some of the ideas are (two coach HSTs, 3rd rail shoes on HSTs...), there's not going to be a lot of lines that fit all of these criteria:
- Require 100/110/125mph trains
- Are not electrified
- Have sufficient platform capacity at termini to accomodate two power cars on each train (e.g. Glasgow Queen Street)
- Are not so busy that they can afford to have sufficient platform capacity at termini to accomodate two power cars on each train (e.g. Waterloo - Exeter needs all nine/ten coaches to be passenger accomodation - a multiple unit could fit a lot of extra passengers into the space that power cars take up)
- Don't need to split/join en route
- Don't have regular stops (given how poor HSTs are at pulling away)
- Need long trains (at least five coaches long, say?)
- No/few platforms that are significantly shorter than the train (okay on one or two trains a day, like the Highland Cheiftan, but not ideal on more frequent services)
- No interworking with services that don't meet these criteria
