Citations as footnotes in biblatex

Question

I would like to improve the appearance of citations as footnotes. I attach the minimal code, containing an example of what I get and of what I would like to end up with:

\documentclass[10pt,a4paper,oneside]{article}
\usepackage[utf8]{inputenc}

\usepackage[
style=footnote-dw,
backend=bibtex,
autocite=footnote,
singletitle=false,
doi=false,
isbn=false,
url=false,
date=year
]{biblatex}
\DeclareFieldFormat{pages}{\mkfirstpage{#1}}
\addbibresource{\jobname.bib}

\usepackage{filecontents}
\begin{filecontents}{\jobname.bib}
@article{Article1,
Author = {Alice, A. and Bob, B. and Charlie, C.},
Journal = {Nature},
Month = {01},
Number = {456},
Pages = {1234-1239},
Publisher = {MyPublisher1},
Title = {Title1},
Volume = {123},
Year = {2000}}

@article{Article2,
Author = {Alice, A. and Bob, B. and Charlie, C.},
Journal = {Nature},
Month = {02},
Number = {789},
Pages = {1234-1239},
Publisher = {MyPublisher2},
Title = {Title2},
Volume = {987},
Year = {2000}}
}
\end{filecontents}

\begin{document}

\noindent What I see is:

I want to cite \cite{Article1}, then both \cite{Article1,Article2}, put footnotes\footnote{This is a footnote}, cite them again\cite{Article1,Article2}.

\vspace{20mm}
\noindent I would like things to appear as:

I want to cite$^{1}$, then both $^{1,2}$, put footnotes$^{3}$, cite them again$^{1,2}$.


\vspace{10mm}
\noindent or as:

I want to cite$^{[1]}$, then both $^{[1,2]}$, put footnotes$^{[3]}$, cite them again$^{[1,2]}$.


\vspace{10mm}
\noindent with in the foot:\\
$[1]$ A. Alice, B. Bob and C. Charlie, "Title1",  Nature 123, 1234 (2000).\\
$[2]$ A. Alice, B. Bob and C. Charlie, "Title2",  Nature 987, 1234 (2000).\\
$[3]$ This is a footnote

\end{document}

Do you have any suggestions?
