Changing eshop base from index.php to indexXYZ.php

I’m running 4.6.0 CE and the base URL of the shop is my domain.com/index.php.
Is there a way to change the index.php to other filename, e.g. index-eshop.php?
(reason is I need to use index.php as a default landing page, powered by WP).
Thanks!

please do not …

maybe like this …

domain.com/eshop/index.php > Shop
domain.com/eshop-blog/index.php > blog

blog.domain.com
shop.domain.com

Good morning,

independent from the technical point of view IMO, it is dangerous to not encapsulate both systems completely for simple security reasons. Imagine one of your WP modules is not secure and an attacker gets full access to your server. In this case you can’t guarantee for the data of your users any more. Please consider to do as Alfred said, even it this would mean to spend a bit more money on hosting…

Cheers
