Override All WordPress Error Redirects

Been searching for a while and can’t find an answer to this that doesn’t involve using wp_die_handler and writing countless lines of unnecessary code, so…

I simply want to override (completely) how WordPress handles error pages, and let Apache handle it rationally via htaccess. WordPress seems to redirect all http errors to a 404.php in your theme. I already have a nice setup for dynamically generating error pages and only need to point to this in htaccess. Works fine on custom sites, fails in WordPress.

Any way of doing this?

As an example, the below code is all that is needed in .htaccess for Apache to properly redirect one to custom error pages.

ErrorDocument 400 /errors/error_page.php
ErrorDocument 401 /errors/error_page.php
ErrorDocument 402 /errors/error_page.php
ErrorDocument 403 /errors/error_page.php
ErrorDocument 404 /errors/error_page.php
ErrorDocument 405 /errors/error_page.php
ErrorDocument 406 /errors/error_page.php
ErrorDocument 407 /errors/error_page.php
ErrorDocument 408 /errors/error_page.php
ErrorDocument 409 /errors/error_page.php
ErrorDocument 410 /errors/error_page.php
ErrorDocument 411 /errors/error_page.php
ErrorDocument 412 /errors/error_page.php
ErrorDocument 413 /errors/error_page.php
ErrorDocument 414 /errors/error_page.php
ErrorDocument 415 /errors/error_page.php
ErrorDocument 416 /errors/error_page.php
ErrorDocument 417 /errors/error_page.php
ErrorDocument 500 /errors/error_page.php
ErrorDocument 501 /errors/error_page.php
ErrorDocument 502 /errors/error_page.php
ErrorDocument 503 /errors/error_page.php
ErrorDocument 504 /errors/error_page.php
ErrorDocument 505 /errors/error_page.php
