Here are some of my ideas, with little-to-no regard to practicality:
[[*]self-sealing: when not pressurized, both stages of the regulator would be self sealing, so it could be rinsed (or even dropped off a boat!) with no water incursion
This exists for first stages. Not needed for seconds.
[*]built-in analyzer: the 1st stage would have a built-in O2 and CO analyzer (upgrade for trimix?), with an LED readout for O2 %, MOD and an audible alarm for CO
Not just no. Hell no. Regs are super reliable and last forever with reasonable care because they are simple mechanical devices. Keep the electronics separate.

That said an inline device that went on the hose between the first and second stages and reported to your computer or a HUD could be cool. Basically rebreather tech for open circuit.
[*]built-in diagnostics: the 1st stage would have diagnostics recording/displaying the efficiency of gas delivery through the primary LP port, as a measure of whether the regulator needs service
See previous. Also, you can do this already with a $15 IP gauge.
[*]built-in dive logging (date, time, depth, gas analysis, gas pressure over the duration of the dive, water temp, gas allocation -- LP port 1, LP port 2, etc -- to more accurately record SAC vs gas used for the BCD or inflating an SMB, etc)
[*]all electronic functions would be powered via a rechargeable battery in the 1st stage that is powered via a gas turbine (windmill) -- when pressurized and delivering gas, the regulator recharges it's own battery
All of this would necessarily reduce breathing performance and decrease reliability. Filling your BCD is a negligible use of your gas. You use around 1500 liters of gas during a dive. Maybe 10 of those go into your BCD. And if you fill your DSMB at depth, it's either a few liters or nothing if you do it by exhaling.
[*]the 2nd stage would have a long exhaust -- think a corrugated tube that mechanically attaches to the outside of the LP hose, with exhaust bubbles exiting behind the diver's head, near the 1st stagen
Would greatly increase work of exhalation.
[*]quick-disconnect hose fittings at the 1st stage, so that the regulator set can easily be disassembled and packed compactly for travel
Currently this requires one thin wrench. Not worth the complexity and risk of failure to replace this with a quick disconnect.
[*]10-year/500 dive normal service intervals
The materials, with the possible exception of valve seats, are capable of this now. The common current 2 year or 200 dive interval is to to catch stuff like a clogged filter or salt crystal intrusion into threads from causing breathing problems or making the reg unserviceable.
 
Always been a bit bothered by AI transmitters hanging out the side of the primary. They look cludgy and delicate. Might be nice to have the electronics tucked away safe in the solid brass housing itself, although permanently tying the reg to a particular brand or standard of computer would be a big risk. Would also like to see CO and O2 analysis in addition to pressure, instead of manually testing with a separate gadget beforehand.
 
Since we already have perfectly good regulators for well less than $1000. , a $2500. regulator is just for people who own $100,000. cars.
Actually a top notch regolator is less than 500 eur, including a decent octopus:
I really don't see how one can spend more...
 
It would need to do pleasant things to my SACk
