I've already maxed out the stem raising and angle with adapters similar to the ones you mentioned. Really need a high profile straight bar, and will probably have to lengthen cables. Too bad they don't make Tiagra hydraulic levers that definitely fit, huh?
I know that this is an old thread but I thought that I would revisit this with some additional options for any one in the same boat as there is really no way to convert the bike to a straight bar due to the brakes and brake levers. Believe me I tried. You would have to change out the entire brake system.
Here is a 70 degree adjustable stem that I came across which is 10 degrees more angle than what was previously available.
And you can buy short reach drop handlebars with a rise from anywhere from 10mm to 50mm-

View attachment 132385Greydog, thanks for the added info... I ended up with a squirrelly-looking hybrid Mcgiver approach that actually worked for my old back...
Thank you Greydog for letting me know... Will check these out - TodHey Todbar, my son found an adjustable bike stem that can go straight up vertical. Scroll down to the bottom of the link to see it set vertically.
You could also use a stem extender-
Also, here is a link to a set of drop handlebars that has a 5cm (2") rise. It also has a very short drop of 100mm and a very short reach at 63mm. This paired with that stem may be just what you need instead of the McGyver Straight bar set up.
