Understanding the でも in 「突っ切る時に万が一子供を轢きでもしたら大変である。」


Consider

> でも突っ切る時に万が一子供を轢き **でもしたら** 大変である。
>
> But, if by chance when I break across, it would be awful if I were to run
> over a kid.

I'm trying to understand what the でも means in でもしたら. The author earlier
states:

> **でもしたら** or でもしようものなら--"(even) if you were". **This pattern attaches to the
> 連用形 of a verb.**

I'm assuming the でも is _not_ the conjunction particle ("but"), but rather でも =
((the て-form of だ) + も)? So a slightly more literal translation becomes
something like:

> But _even_ (でも) by chance running over a kid, if it would be done (したら),
> would be bad.

Is this the case?

Then, this "is-even" (でも) is used to convey a [sense of hoping that something
doesn't come
true](https://japanese.stackexchange.com/questions/48176/explanation-

This でも is neither a conjunctive nor `で + も`, but a particle meaning "～ or
something".

轢きでもしたら is 轢いたら with でも added. If you know [how to attach a contrastive-wa (or

follows the same pattern of `連用形 + particle + する`.
