Off the top of my head:
~
Ottoman Empire; guided carefully by Abdul Pasha to control all of Arabia, Iran, large chunks of the Caucasus and Central Asia (in addition to Balkan, Medi and probably substantial African holdings).
~
Russian Empire; controls whatever they can wrestle out of the super-Ottomans. Let's just say parts of northern Kazakhstan, some of the Northern Caucasus, Siberia and Far East Asia.
~
Afghanistan; TTL's version of the Durand Line most early and ethnically cohesive. Short-term frustration for the British, long-term boon against tribal politics for...
~
India; no partition (India, Pakistan, Bangladesh), Sri Lanka, Maldives and Nepal either integrated early on or muscled into some sort of federation. Bhutan can be a protectorate with either no army or a poor military force. Burma also attached, and only kept through Indian government keeping the various tribes and ethnicities constantly fighting amongst themselves. Perhaps Upper Burma heavily influenced by Super China.
~
Thai Empire; controlling all of Laos, Cambodia and what is now Central and Southern Vietnam (populated by mix of Vietnamese, Cambodians and Champa ittl).
~
China; almost all of historical China. Outer Mongolia, Outer Manchuria, parts of Kyrgystan, Southern Tibet. Northern Vietnam a very restless set of provinces who've fought and lost several independence wars.
~
Indonesia; all of Indonesia, Malaysia, Brunei.
~
Philippines; all of OTL Philippines.
~
Japanese Empire; all of Japan, Kurils, Sakhalin, Ryukyus and Taiwan.
~
United Korea; though it could be absorbed by Japan and there'd still be room.
PoD could probably happen sometime around the earliest period of English colonization of India and whenever decolonization comes around, less successful pro-Muslim movements and control over Burma given to Federation (never split apart, even though it makes sense). Have the French out-maneuver the English and take Thailand rather then settle with breaking pieces of it off, an earlier Meiji, a China with some competent emperors who try to pull the same thing and let the Ottowankers sing their praise and behold- this.
Would not want to live in this world though.
Here's a rough outline of what the map might look like (Afghan/Kazakh/Ottoman borders not "real' but whatever, I made it in like 5 minutes). Included only the areas indicated by OP.
