I'm back after many a moon. I just have these cyclical urges to create dungeons and use this marvelous engine we all love so much

My latest design, The Chronicle of the Five Stones, is my most ambitious project by far. I want it to appeal not just to people in this community, but also those who have never played Dungeon Master before.
I have it all planned out, but I need some help with programming and expanding on the RTC engine to fulfill all my creative desires.
Features I need added to the engine:
i) Text / picture screens: I need a trigger that freezes the game and brings up a screen of text.
ii) Avatar-heroes who can be summoned for a limited amount of time before disintegrating.
iii) Alignment specific weapons and items (i.e. Syrahad the Cleric may not use Shadow weapons). Also certain weapons / items can only be wielded by those destined to wield them.
iv) Barding: An idea I got from Betrayal at Krondor: Play an instrument in an inn / drinking pit and get coins. Also a nice excuse to record some of my midis

v) Portals between levels: Summoned by a horn at places marked by the eight-legged horse, the steed of the unseen paths can take you between levels. This will need a separate screen showing all the potential places to 'portal' to, and some kind of 'animation', racing through the void.
vi) Regenerating enemies - I need to programme bosses who regain a little health every second. You need serious firepower to take these guys on. Also some AI to make bosses flee when their health is running low and just generally more interesting.
vii) Rune-charging / blessing weapons: time-limited bonuses for weapons blessed and / or charged.
viii) Re-charging magick weapons which run out of charges
---------
Are these things easily programmable? Is anyone up for helping me with them, as they can also be used by other designers too.
I can't wait to start on this project. Set in my Nodewheels Universe, it is going to add a novel-reading element to the glorious world of Dungeon Master
