There's nothing inherently wrong about offering your own translations, even if they are of the lowest quality, as it is likely that there will always be some who will appreciate the effort [even if they are likely in a very, very, very, very tiny minority, considering how abysmal machine translations are when it comes to eastern languages].
However, please keep in mind that taking over the chapter order of proper translation teams is rude to both other translation teams [as it obsfucates their efforts] and to readers [who then have to dig past substantially different work in order to pick out the normally progressing translations]. Please consider utilizing a different volume/chapter presentation [than the preexisting translations use], so as to easily sort your work out from the rest.
