From my very limited/superficial knowledge about Shah Waliullah R.A, he somewhat saw a reconciliation between all the four mazaheb. And i think his foresight was very powerfull into this matter as he had studied for quiet sometime with ulema of different mazaheb in his time spent in Hijaz. With his vast exposure and high calibre with brilliant intellect, although in aamal he called himself hanafi, but when he writes he doesnt stick to hanafis positions only, infact he often prefers the Shafi positions. And even in Aqeeda he is known as ashari, but have praised the muhaditheen and does state in places that he prefers that taweel of sifat should not be done. But have done it in some places in Hujjatullahil Baaligha for explanation.

He holds Shaykhul Islam Ibn Taymia R.A at a very high and lofty position, and sort of sided with him in some stances when it comes to Ilm eKalam. I think in the end he understood where everyone is comming from, what everyone intended, where there were miscommunication, and how ulema e haq with all their differences, land on the same page.

Also, alot of people ask what was his tajdid, so basically, his tajdid was that he explained the whole deen with the logic and wisdom behind Allah's command, because what was happening in his time and the time to come was that he realized that people are asking questions based on intellect , and the attitude is changing, so he wrote Hujatullahil Baaligha which explained the Deen, not by simply stating the Ahkam, but by explaining the whole background scene, the logic and wisdom and the effects of our actions. And such explanation were all given from the quran and Hadeeth. And this results in the iman getting more stronger. Similarly, he explains the crux and jist of Tasawuff, and exactly tells what this science is about,and then the wisdom behind the Azkars. He provides a very clear understanding of the Deen , rather than just stating the Ahkam of deen.

So overall, he was just brilliant, and a man who understood his deen and taught people a crystal clear deen, and through his explanations Iman on Quran and Sunnah become strong and was revived in the form of his Sons and students who affected the whole sub-continent and beyond.
