To make any Japanese voicebank sing English lyrics, you will need to approximate the sound of English phonemes using Japanese samples.
You will first want to become familiar with English phonemes. English spelling is not an exact indicator of how words are pronounced, so you will need to think carefully about the actual sounds and not the letters. This is a chart of English phonemes that compares various transcription systems and provides example words for the pronunciation: https://arpasing.neocities.org/en/resources/phoneme-chart.html

From here on out, I will be using X-SAMPA, since it corresponds directly with the standard International Phonetic Alphabet.
These are the monophthongs (single vowels) that can be approximated with Japanese.
a: A, V, Q, @
i: i
u: u
e: {, e, E, I
o: Q, o, O, @`, U
The vowels "i" and "u" only have a single vowel under each due to the fact that they are high/close vowels. The English vowels I and U are more open, so a more open vowel will sound more natural, especially in a singing context.

For diphthongs, you will need to mainly have a long first vowel and a short second vowel.
aI: a + i
eI: e + i
OI: o + i
oU: o + u
aU: a + u
e@: e + a
For syllables ending with R or L, I highly recommend using a short "o" at the end instead of a short "ru".
Given that you're interested in using CVVC voicebanks specifically, you can easily achieve this by changing the vowel in the VC note. For example, the word "mine" would be input as [ma][i n].
In some situations, it might sound more natural to use the first vowel only, especially in very short syllables.

These consonants are present in English but not in Japanese.
D: use z or d
5: use o
l: use r
r\: use w
T: use s
Z: use dZ or S
