Please help with a Christmas present.

I would like to upgrade a friends bike with some [much] lower gears as a
Christmas present. Currently he is operating with a Shimano Ultegra
system;

10 cog cassette.
Dual control levers.
Bontrager freehub.

To the best of my knowledge that limits him as to around 25 teeth
largest cog. I would like to be able to equip him with large cog of no
less than 30 teeth preferably 32 or better yet 34.

I would also like to make the change as simple as possible. Limiting it
to cogset, derailler and chain would obviously be perfect. I would
prefer not to have to change the brifters, and a new hub is not an
option. And before you say it, triple cranks are not an option. his rear
triangle geometry is too tight for it to really work well and he has no
interest in a triple even if it could, I've asked (more than once)

What would be the best way to go? Can it even be done or a I just
whistling Jingle Bells?

Holy moly - I thought it was gonna be an old 7-speed or something for
a kid w/ no bike. Heck, I'm years away from affording that kind of
technology for myself.

(I have a worn CS-61 or such 9-speed w/ 32 teeth you can have for
shipping. I'd even throw in a worn chain that doesn't skip too bad on
the 13.)

Given the constraints you have imposed it would seem that the only
option is a long cage Shimano derailleur (to match the shifters) with
a 10 speed SRAM cassette.
There is also:

You would undoubtedly need to add a longer chain.

I have no idea how well that might work. In any case "well" is a
subjective term.

Yeah, an SLX cassette will do it. Longer chain. See how bad the sag is
before putting on a longer cage mech.

Buy a 10 speed Shimano ATB cassette and a long caged road derailleur
(they match the existing brifters)

SRAM Ten cassettes go to 28t, IRD to 34 teeth.

Santana tandems use the IRD Ten cassette with a 34 and
Shimano MTB rear changer. Shifts great. Save yourself some
aggravation and just get a new chain with your new cassette.

Geez, MSRP on that is $399, probably mid-$300 anyway. Yikes!

What do you expect for something that has a 9 hour(!) machining
process?

They do have less expensive models.
