I do wish they scratch it coz 11356 design has upgrade potential. The modified design (if at all they do go ahead) will be in consultation with the designers themselves. A modified/upgraded 11356 is not something which is not doable. Not exploring the possibility to enhance the capability of 11356 will be foolish.
After all what are we looking at with this kind of upgrade -
1) A new integrated mast or atleast a mast which can accommodate/integrate multi faceted radar arrays and other systems.
The below pic shows Indian Navy's two 11356 under construction, one with its mast installed and another one without it. A new mast integration would most probably be like plug-n-play, the main stuff to be looked into is if the present electrical systems have the capacity to cater to the (increased) loads from the new radar and electrical systems.
2) Inserting a new hull section aft of the exhaust stack (adjacent/in front of the hanger)
For a 124m long ship, 6m hull section is a far less complicated stuff than proofing an equally long hull section for a sub-70 meter submarine. I'm talking about the design of AIP module and VLS module for submarines. Below is a hull section of 11356 and If my estimate based on the beam of approx 15m is correct, we are looking at a hull section thats around 6m in length. Its not a full size section though.
With a new/integrated mast, the area behind the bridge structure can be cleared with the boats and lauch arms being shifted to the new hull section and alongside the new VLS area.
^^ This is the place where additional Uran canisters (those 8-cell version we see with BAL coastal units) will be installed which can number 16-32 depending on space. Now all targets don't need Yakhont/Klub/Kaliber treatment and can be accomplished with 260Km range Urans, like striking those international terrorists inside Syria.
Hull extension? Can you even do that without affecting performance?
If yes, then I got some sweet ideas for 22800 Karakurt.
Why should we be so much worried about performance. I don't think its going to make much difference.
Btw, we also need to take note that for any future ships we are looking at new and powerful gas turbines like M75RU (6000-7000 hp), M70FRU (12000-14000 hp) and the 27,500hp M90FR.
A new version of 11356 can either retain COGAG (premium propulsion system) or go with more economical CODAG (termed as poor mans propulsion) like that of 22350.
Then there is shafting (very important part and specialized) which will also see lengthened... haven't heard about any vibrations issues caused due to improper alignment of the shaft from the Russian side, so no worries. Yantar makes shafts inhouse.
Btw, I'm interested in hearing your ideas on 22800.
