Can general relativity be constructed with differential forms?

Yes, it can. See for example Takahara's book on mathematical physics.

I'm coming up empty on a search for Takahara in the categories of physics or mathematics.

Try Nakahara.

Try Nakahara.

On Amazon, I found the text Geometry, Topology and Physics, Second Edition (Graduate Student Series in Physics), M. Nakahara.

To be clear, does Nakahara express general relativity in terms of differential p-forms rather than simply differential equations?

thanks, in advance.

Can general relativity be constructed with differential forms?

It can. With bundle-valued differential forms and bundle connections. You will need to use exterior covariant derivative.

Of course you can, try N. Straumann's book: General Relativity with applications to astrophysics. In some place around chapter 2, he work with the tetrad formlism and he have an entire part of Differential Geometry.

Greetings!

Straumann does it without fibre bundles, but on p. 111 has a footnote addressed to readers familiar with fibre bundles, so that they will recognize what he is doing using the language and the tools that are familiar to them.

I hope I don't mispell their names, but if you have access to Physics Reports, there's a famous review article by Eguchi, Gilkey and Hanson that I would also reccomend for your attention.

"Gravitation, gauge theories and differential geometry", Tohru Eguchi, Peter B. Gilkey, Andrew J Hanson, Physics Reports 66 no 6 (1968) 213-393. Section 3 deals with Riemannian manifolds.

Yes; Here is a textbook on field theory and entirely written in the exterior calculus format :
