No. But they would likely negotiate the best deal possible, then passive-aggressively sabotage or ignore harmful portions. They were able to do this in many regards even in OTL - as were the Balkan States. For instance, the newly independent countries were supposed to assume a proportionate share of the Ottoman debt - didn't happen. Rumania was required to emancipate the Jews as a condition of independence. Also didn't happen. Bismarck for a time withheld German recognition, but only as a ploy to achieve a totally different objective. The Ottomans were supposed to carry out "refoms" in "Armenia" (i.e. hand the provinces over to Christians), but managed to squirm out of that. When it comes down to it, the Powers will only care about what is in their interests. An empire that managed to defeat Russia will be weighed differently in the Balance of Power, and I think relations with the empire will be considered more important than the level of autonomy of Bosnian Christians, for example.
I think the types of demands likely to be made are going to be face-saving. For instance, a commission to review administrative practices in the Balkans and write a report on required reforms. Abdul Hamid was very determined to settle the debt issue, and that happened in OTL, and was the main issue of concern to everyone in any case. There are positives and negatives here as well. On the one hand the continued unity of the empire is in the interests of Western bondholders, but on the other hand, they tended to resist financial reform as inefficient tax collection reliably delivered to them was preferable to the risk of a reformed system.
With regard to Pan-Slavism, I don't think all forms of Slavic nationalism are out, but as a universal movement led by Russia, it would be over. More likely local movements would still be around, like South Slav nationalism, but that is easier to deal with and is even a source of potential cooperation - and conflict - between the Ottomans and Hapsburgs.
